The Honda 14721-ZDJ-900 Exhaust Valve is a genuine OEM component designed for EB2200 and EU2200 inverter generators and the GXR120 horizontal shaft engine. As a direct Honda OEM part, it is manufactured to the same specification as the valve installed at the factory, ensuring correct seating geometry and proper sealing in the combustion chamber. Honda supersedes parts at serial breaks, so confirm your unit's serial number against the fitment table before ordering. This Exhaust Valve is the correct choice when a worn or burned valve is causing compression loss, rough running, or excessive exhaust emissions in your equipment.
Key Features
- OEM Combustion Sealing — genuine Honda construction ensures the valve face and seat geometry match the cylinder head exactly, maintaining the compression needed for clean, efficient combustion
- Direct OEM Replacement — this Exhaust Valve drops in as a like-for-like replacement with no machining or adaptation needed when fitted to compatible units
- Broad Fitment — covers EB2200 and EU2200 inverter generators as well as GXR120 horizontal shaft engines; verify your serial number against the fitment table to confirm the correct application
- Restores Lost Compression — a worn or burned exhaust valve allows combustion gases to blow past the seat, robbing power and making the engine hard to start; replacing it returns full compression and smooth operation
The exhaust valve controls the exit of spent combustion gases from the cylinder. It opens at the end of the power stroke to allow exhaust gases to escape, then closes tightly before the next intake charge enters the cylinder. A properly seating exhaust valve is essential to maintaining compression — if the valve face or seat wears, burns, or pits, compression drops, the engine loses power, idles unevenly, and may become difficult to start. Replacing a worn Exhaust Valve with a genuine Honda part restores proper sealing and brings combustion efficiency back to specification.
